1.正壓送風口應用在電影院內(nèi)時：配電房通道的雜物應該全部清理干凈，對報警系統(tǒng)部分損壞的零件必須進行更換，樓梯口的正壓送風口要安置妥當，同時電影院應增加一些應急燈。

1 positive pressure air used in the cinema: distribution channel debris should clean all parts of the damaged, alarm system must be replaced, the stairs of the positive pressure air supply outlet to place at the same time, the cinema should increase the number of emergency lights.

2.正壓送風口應用在電腦機房內(nèi)時：可以保證機房內(nèi)換氣次數(shù),保證機房空氣參數(shù)。由空調(diào)送風口從下面送入靜壓箱,靜壓箱寬度大于2-3倍空調(diào)送風口尺寸，主機房內(nèi)部維持正壓不宜小于5Pa。

2. when the positive pressure air supply is applied in the computer room, it can guarantee the air change in the engine room and ensure the air parameters of the engine room. The air outlet from under static pressure box, static pressure box width is 2-3 times larger than the air outlet size, the host housing internal pressure to maintain not less than 5Pa.

3.正壓送風口在建筑樓梯應用時：在具體的工程設計上，相關(guān)消防設備應包括建筑樓梯間全部正壓送風口、著火層及上下相鄰層的排煙閥(口)、電動防火門、防火卷簾門等。消防控制系統(tǒng)無法聯(lián)動；未設置室外消防給水設施；電梯前室未設置正壓送風口等火災隱患，規(guī)范強調(diào)消防電梯前室正壓送風，以提高前室風壓的方法來達到阻止煙氣進入的目的。

3 positive pressure air in the application of building stairs in concrete engineering design, fire protection equipment should include building. All the positive pressure air inlet, exhaust valve and ignition layer on adjacent layer (mouth), electric fire doors, fire shutter doors etc.. The fire control system can not be linked; outdoor fire water supply facilities are not set; the elevator is not set to send positive pressure air and other fire hazards, fire elevator room standard stressed the positive pressure air. In order to improve the method of anterior pressure to prevent smoke from entering the objective.
